Abstract
A broach tool includes a broach tool rake face with a tailored surface topography.
Claims15
A method for manufacturing a broach tool comprising:
- identifying an application regime for which a tailored surface topography is to be used;
- determining the tailored surface topography for the application regime, the tailored surface topography including a combination of depressed wells, microchannels, grooves, pockets, dimples, pyramids, and ovals to be formed in a broach tool rake face of the broach tool and selected to control a coefficient of friction between the broach tool rake face and a workpiece;
- selecting an appropriate processing method to form the tailored surface topography in the broach tool rake face;
- and
- forming the tailored surface topography in the broach tool rake face using the processing method.
